    Should I have it checked out before I fire it up?

    Looks good from here :)

    If you dont have a tube tester and want to be careful - open it up and if nothing looks burned or smells funny - turn it on and if it lights up and doesnt make any unusual sounds - go to town.

    The bias on the ones I have was dead on - as set from the factory.

    I assumed that the seller said it was working? If so, typically the only possible problem would be caps (hum or ghost notes) or bad tubes.

    Usually the sockets need to be retentioned in these - if you dont know the safety protocols have it done for you.

    Well - as I said above. I dont see any reason to be overly cautious. I have never had an amp blow up just by turning it on - YMMV :lol:

    Congrats on a great amp!

    That little dude is over 40 years old.
    I would definitely take it to the Amp Doctor ASAP, just for peace of mind.

    My PR is a 67. I take it in every 2 years, weather it needs it or not, just cause it's old, and I love it, and I want to continue to use it for a very long time.
    Usually, he finds a resistor or two that are going bad, just little things. My resistors are 50 years old. They can't last forever.
    It's money well spent.

    Run the speaker number thru google - it looks like a ceramic CTS but is hard to see. I am LOVING the Eminence Copperhead in this amp.

    BTW - that tattered tolex can be glued down real easy. Go to Home Depot and get the smallest bottle of contact cement; ~$5. Put a dab on the tear and one on the cab. Let it dry per the instructions and press it on. The tears on mine are now undetectable.

    A little tip. My voltages were way high in mine so I dropped in a 5v4 rectifier and it put them dead on spec. Also, same here with bias. I tried mine with 3 different matched sets, new and NOS. it came in dead on without changing anything.

    It's an Oxford. Great speakers, despite the bad rep the later 12"-and-up models get. They never changed the 10" models, so they're always desirable. I have four of them in a Super Reverb.

    FWIW I've repaired at least a dozen that have, some stored for a long time - and some just purchased. If you don't know how to check an amp out yourself any tube amp over 10 years old *should* be checked out - any over 20 absolutely. Again, if an older amp has been stored for long periods of time it's more likely to have crystallized filter caps. If one blows you can lose a transformer - both an expensive repair and a repair that devalues the amp.

    It's just not worth NOT being cautious.

    Also, a tube tester is pretty useless for guitar amp tubes. Used ones you can find do not hit the tubes with plate voltages used in guitar amps - power tubes only get 185VDC max. It's simply not enough to stress the tubes like a guitar amp and it's impossible to use one to judge how good tubes are - or to try to match them.

    Also, unless a tube tester has been calibrated fairly recently it is very unreliable. Well-know guitar tube sellers use custom-built or extremely expensive, high-voltage testers - not the kind you can find an electronics swap meet or eBay.

    Silverface has tons of knowledge and experience. I'd take his advice. Once you get things right, you will have a top flight amp that has been a standard for decades. As I've said before, it's tough to beat a Princeton Reverb.
